Polymers with micro- and mesoporous structure are promising as materials for gas storage and separation, encapsulating agents for controlled drug release, carriers for catalysts and sensors, precursors of nanostructured carbon materials, carriers for biomolecular immobilization and cellular scaffolds, as materials with a low dielectric constant, filtering/separating membranes, proton exchange membranes, templates for replicating structures, and as electrode materials for energy storage. Sol-gel technologies, track etching, and template synthesis are used for their production, including in micelles of surfactants and microemulsions and sublimation drying. The listed methods make it possible to obtain pores with variable shapes and sizes of 5-50 nm and achieve a narrow pore size distribution. However, all these methods are technologically multi-stage and require the use of consumables. This paper presents a review of the use of macromolecular architecture in the synthesis of micro- and mesoporous polymers with extremely high surface area and hierarchical porous polymers. The synthesis of porous polymer frameworks with individual functional capabilities, the required chemical structure, and pore surface sizes is based on the unique possibilities of developing the architecture of the polymer matrix.
具有微孔和介孔结构的聚合物有望用作气体存储和分离材料、控释药物的包封剂、催化剂和传感器的载体、纳米结构碳材料的前驱体、生物分子固定化载体和细胞支架、低介电常数材料、过滤/分离膜、质子交换膜、复制结构的模板以及储能电极材料。溶胶-凝胶技术、径迹蚀刻和模板合成用于其制备,包括在表面活性剂和微乳液的胶束中以及升华干燥过程中。所列方法能够获得形状和尺寸可变(5-50纳米)的孔,并实现窄的孔径分布。然而,所有这些方法在技术上都是多阶段的,并且需要使用消耗品。本文综述了大分子结构在合成具有极高比表面积的微孔和介孔聚合物以及分级多孔聚合物中的应用。具有独特功能、所需化学结构和孔表面尺寸的多孔聚合物骨架的合成基于聚合物基体结构发展的独特可能性。
